Answer:

Carbondioxode is present in the atmosphere which is used by plants during the process of photosynthesis. From this process, plants make their food by using carbondioxode from the air for making glucose. The carbondioxide is released in the atmosphere by the animals during respiration process and the carbon concentration is stable.

Increase occurs in carbondioxide concentration due to human activities such as use of fuels in vehicles and industries.

Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon, but that need is also entwined with one of the most serious problems facing us today: global climate change.

<h2>Point mutation.</h2>

Explanation:

  • The protein will be unchanged.

Mutation is defined as a change in nucleotide sequence of a gene. When a single nucleotide is inserted,deleted or substituted in a DNA sequence, then the resulting mutation is classified as point mutation.

A gene contains two region- intron region and exon region.

The region that codes for a particular protein is called the exon and the region that separates two exons  and does not code for any protein is called the intron.

Most of the point mutations in the intron region are silent except if it is located at the splice site recognition sequence.

In the given situation the mutation is in the middle of the intron region so there is no chance of it being a splice site recognition sequence.  Hence the protein will remain unchanged.

We should remember that we should consume all necessary nutrients at a correct amount and proportion. this includes the primary food substance carbohydrates, fat and protein. and protective food substance in a small amount, which includes mineral ions ( iron, calcium etc) and vitamins. Also we have to take in enough water (6-8 cups a day) and fibre to prevent deficient diseases and to maintain health.
in addition, note that the amount of food intake varies with age, sex, body status, daily activity etc. For example, teenagers and pregnant women should increase all necessary nutrients intake to ensure proper growth and development of ourselves or the baby.
